Isocrates
Isocrates (436-338) was a leading Attic orator, and a highly influential teacher of rhetoric. From a wealthy family, he received his education at the hands of leading rhetoricians and statesmen such as Gorgias, Theramenes, and Prodicus. He began his career as a logographer in the 390s, but then began training others in rhetoric. Many of his surviving works are rhetorical exercises. A believer in pan-hellenism, his Panegyricus (ca. 380) called for Greece to unify under the command of Athens and Sparta. He built on this theme in the Philippus of 346, again calling for pan-hellenic unity, now under the command of Philip II. But in his last great treatise, the Panathenaicus, he abandoned this theme and instead glorified Athens. After the Greeks were defeated by Philip in 338, Isocrates wrote to Philip urging him to implement the program of the Philippus, and died later that year.
